Why can’t ordinary software tools restore files from RAID?

Conventional hard disks keep user’s data by writing it to their surface in a consecutive way, and this is how an entire file is stored on a single hard disk. However, when data is written to a RAID system, a file is divided into several parts. Then these parts are written consecutively to all hard disks within such array. The size of such parts may range from 2 KB to 2 MB, so each file is stored on several hard disks at the same time.

Such approach helps to speed up read and write operations, and it is evident that saving two parts of a file having the size of 1 GB to two hard disks simultaneously is much faster than saving the same 1 GB of data to one hard disk. However, this peculiarity makes file recovery more complicated.

Various RAID levels store information in different ways. Additionally, manufacturers like QNAP also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

How can the use of specific file-sharing protocols impact data loss risks on NAS QNAP Turbo Station TS-431 / TS-431+ devices?

The use of specific file-sharing protocols can impact data loss risks on NAS QNAP Turbo Station TS-431 / TS-431+ devices in several ways:

  1. Encryption: Some file-sharing protocols offer encryption options to secure data during transfer. Using protocols with encryption, such as SFTP (SSH File Transfer Protocol) or HTTPS, can reduce the risk of data interception and unauthorized access.
  2. Access Control: Certain protocols provide more robust access control mechanisms, allowing administrators to define permissions and restrictions for different users or groups. By using protocols like NFS (Network File System) or SMB (Server Message Block) with proper access controls, the risk of accidental or unauthorized data deletion can be minimized.
  3. Vulnerabilities and Exploits: Different file-sharing protocols may have varying levels of security vulnerabilities. It is crucial to choose protocols that are regularly updated, well-maintained, and have a strong security track record. Using outdated or insecure protocols can expose the NAS device to potential exploits, increasing the risk of data loss.
  4. Data Integrity: Some file-sharing protocols, such as BitTorrent or FTP (File Transfer Protocol), do not have built-in mechanisms to ensure data integrity during transfer. This can lead to corrupted or incomplete files, increasing the risk of data loss. Choosing protocols that have built-in integrity checks, like rsync or SCP (Secure Copy Protocol), can help mitigate this risk.
  5. Backup and Snapshot Support: Certain file-sharing protocols may offer better integration with backup and snapshot features provided by the NAS device. For example, protocols like RTRR (Real-Time Remote Replication) or rsync can facilitate efficient and reliable backups. Having a robust backup strategy can significantly reduce the impact of data loss incidents.

It is important to consider these factors when selecting file-sharing protocols for NAS devices to ensure data security, integrity, and minimize the risk of data loss. Additionally, implementing other security measures like regular firmware updates, strong passwords, and network segmentation can further enhance the overall data protection on NAS devices.

How to take hard disks out of the NAS and connect them to a PC?

Although NAS Turbo Station TS-431 / TS-431+ can be accessed over the network, you still need to take the hard disks out of the storage device and connect them to a Windows computer. Only in this case will the software be able to scan them properly. Here is what you should do:

  1. Turn off the storage and disconnect it from the power supply.

    WARNING! Before you start taking hard disks out of your NAS device, read the manual carefully. Incorrect actions may damage your network-attached storage and/or the hard disks within the RAID system.

  2. Take the hard disks out of the NAS one by one, carefully removing them from their slots. Remember that the disks are extremely vulnerable: hitting or dropping them may result in serious physical damage.

  3. Make sure to mark each hard disk in accordance with how they were installed inside the NAS.

  4. Remove the hard disks and connect them to the computer. In this video, we have explored what ports are used to connect hard disks, and what to do if there are not enough ports or connectors.

Restoring data with Hetman RAID Recovery

Hetman Raid Recovery

This program recovers data from damaged RAID arrays and is fully compatible with QNAP Turbo Station TS-431 / TS-431+. The hard disks that make up the RAID contain technical information about the algorithm used to save files. When launched, Hetman RAID Recovery reads this information and puts the damaged array together. Then you can open the disk and save your files. Also, you can recover the files accidentally deleted from the network drive.

How to recover data from a QNAP

Turbo Station TS-431 / TS-431+ has 4 HDD slots, and it supports the following array types:

  • RAID 5;
  • RAID 6;
  • RAID 10;
  • RAID 0;
  • RAID 1;
  • JBOD;

NAS supports:

  • ZFS;
  • EXT4;
  • EXT3;
  • FAT32 (External Disk Only);
  • NTFS (External Disk Only);
  • HFS+ (External Disk Read Only);

Safe recovery from disk images

This utility lets you save an entire copy of the disk to file and then work with this image instead of the actual disk. Such feature helps to protect data on the disk from:

  • Overwriting during the recovery process;
  • Loss resulting from bad sectors;
  • User mistakes.

To create an image, do the following:

  1. Make sure that you have enough free space to save the image. The image file size usually equals the disk size.

  2. Select the disk in the main window, and choose from the menu ToolsSave Disk. You can select multiple disks to be saved.

  3. When the image creation wizard starts, you can choose to save the entire disk or select only a part of it. Specify the parameters and click Next.

  4. At this stage, you need to choose a directory where to save the image. Choose any disk connected to this PC, or save the image by FTP.

Where are user’s files stored?

The QNAP Turbo Station TS-431 / TS-431+ network-attached storage keeps QTS (QuTS hero) operating system files on a separate RAID 1 (mirrored) array. Usually, all NAS systems create several volumes on every hard disk, and the first of them takes up to 2 Gb of space. This is where operating system files are stored. Other volumes are united into a RAID array where user’s data is written.
